Lieaeaa To all whom it may concern Be it known that I, HAROLD S. FoRsBnnG, a citizen of the United States, residing at Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Marking Devices, of which the following is a specification.

This invention relates to marking de vices.

A marking device involving my invention can be utilized for various purposes, for instance for spotting or for lining work which may be vof any suitable character. The implement is so constructed in the present case that it is adapted for both spotting and lining. The article is susceptible of general use, although it is of particular advantage when'employed in conjunction with metal working machines having means to adapt it for interchangeable use with various styles thereof.

In the drawings accompanying and forming part of the present specification I have shown in detail one of the several convenlent forms of embodiment of the lnvention which to enable those skilled in the art to practise the same will be set forth fully in the following description. I do not restrict myself to this showing; I may depart therefrom in several respects within the scope of the invention defined by the claims following said description. In this form of embodiment of the invention the appliance is provided with means for its connection as required with either the spindle or arbor of a vertical milling machine or the corresponding part of a horizontal milling machine.

The device is simple in construction, effective in action, can be readily applied and dismounted and can mark with precision and distinctness the work which is to be either spotted or lined or both.

Referring to said drawings: Figure 1 is a side elevation of the device. Fig. 2 is a front view of the same. Fig. 3 is a side elevation of the main section. Fig. 4: is an inside face view of the auxiliary section. Fig. 5 is a top plan view of a collar. Fig. ,6 is a view corresponding to Fig. 1 showing, however a part only of the main section with the tool mounted differently from the manner shown in Figs. '1 and 2Q Fig. 7 is a view corresponding'to Fig. 1 with the forward portion of the main section broken away. Fig. 8 is a perspective View of parts of MARKING DEVICE.

a vertical milling machine. showing my marking device connected with the spindle thereof. Fig. 9 is a similar view of parts of a horizontal milling machine with the main section. of the marking device connected with the spindle thereof.

Like characters refer to like parts throughout the several views.

The device has means for connection with either a vertical or a horizontal milling machine and is also provided with a suitable marking tool which in thepresent case takes the form of a punch. Said device comprises a main section and an auxiliary section. I use the terms main and auxiliary merely as a matter of convenience and for the further reason that the main member carries directly the punch or equivalent marking tool. In all cases this may not be necessary. The members or sections are provided respectivelywith means for con-- nection with arbor-s. For example the, main member may be equipped with means for connection wlth a horizontal arbor, while the auxiliary section or member may be furnished with means for its connection with a vertical spindle or arbor. As will be ob vious I do not restrict myself to any particular construction except as confined by my claims, and with the foregoing general observations what is represented in the annexed drawings.

A main section such as answers my requirements is that denoted by 2. Asrepresented this main section or member 2 is in the form of a ring, being adapted to encircle the horizontal arbor (not shown) of a hori zontal. milling machine and to be clamped to said arbor by the customary collars thereon. Extending outwardly as represented from the ring 2 is the bracket 3 widened at its free end and provided with the sleevesl co- 7 I will now describe in detail adjuncts will be hereinafter more particularly described.

, The auxiliary section or member is designated by 6 and as represented it is in the form of a disk. The two sections or members 2 and 6 are adapted for detachable association. When the device is to be used in connection with a horizontal milling machine, the auxiliary section or member 6 is separated from the companion element, but
